Anchor \An"chor\ ([a^][ng]"k[~e]r), n. [OE. anker, AS. ancor,
oncer, L. ancora, sometimes spelt anchora, fr. Gr. 'a`gkyra,
akin to E. angle: cf. F. ancre. See Angle, n.]
1. A iron instrument which is attached to a ship by a cable
(rope or chain), and which, being cast overboard, lays
hold of the earth by a fluke or hook and thus retains the
ship in a particular station.
[1913 Webster]
Note: The common anchor consists of a straight bar called a
shank, having at one end a transverse bar called a
stock, above which is a ring for the cable, and at the
other end the crown, from which branch out two or more
arms with flukes, forming with the shank a suitable
angle to enter the ground.
[1913 Webster]
Note: Formerly the largest and strongest anchor was the sheet
anchor (hence, Fig., best hope or last refuge), called
also waist anchor. Now the bower and the sheet anchor
are usually alike. Then came the best bower and the
small bower (so called from being carried on the bows).
The stream anchor is one fourth the weight of the bower
anchor. Kedges or kedge anchors are light anchors used
in warping.
[1913 Webster]
2. Any instrument or contrivance serving a purpose like that
of a ship's anchor, as an arrangement of timber to hold a

hold the core of a mold in place.
[1913 Webster]
3. Fig.: That which gives stability or security; that on
which we place dependence for safety.

(called also egg-and-dart, egg-and-tongue)
ornament.
